LINNAEA 387 



AS, 10 or more, often with stds., united at base into a ring; G (2 

 3 5), multi-loc. , often with extra partitions projecting from the mid- 

 ribs of the cpls., but not united to the axile plac. ; ovules i or 2 per 

 loc., pend. , anatr., with the micropyle facing outwards and upwards. 

 Septic, caps., or drupe. Embryo usu. straight, in fleshy endosp. 

 Linum (flax, linseed) is economically important. Chief genera: 

 Radiola, Linum, Hugonia. [BH. chars, incl. ov. i-loc.] 



Linaloa, Bursera delpechiana Poiss. (Mexico). 



Linanthus Benth. (Gilia p.p.). Polemoniaceae. 15 N. Am. 



Linaria Tourn. ex Mill. (BH. incl. Cymbalaria Medic., Elatine Rupp., 

 Elatiuoides Wettst.). Scrophulariaceae (11. 3). 100 *_ and S. Am., 

 chiefly extra-trop. 7 in Brit, (toad-flax), esp. L. Bulgaria Mill, 

 (yellow toad-flax). The pi. is a perennial, each year's growth arising 

 from an adv. bud upon the summit of the root. The fl. is closed at 

 the mouth ; honey is secreted by the nectary at the base of the ovary 

 and collects in the spur. The only visitors are the larger bees, which 

 are able to open the fl. , and whose tongues are long enough to reach 

 the honey. Peloria of the fl. is frequent ; a term. fl. appears upon 

 the raceme and is symmetrical, with 5 spurs upon the C and a tubular 

 mouth. Sometimes fls. of this type occur all down the raceme. 

 Another interesting sp. is L. Cymbalaria Mill., the ivy-leaved toad- 

 flax, found on walls in Brit. Before fert. the fls. are positively helio- 

 tropic and stand erect ; after it they become negatively heliotropic 

 and bend downwards, seeking out the dark crannies in the substratum, 

 where the seeds ripen.
